Programmable Clock Generator
5P49V5927
DATASHEET
Description
The 5P49V5927 is a programmable clock generator intended
for high performance consumer, networking, industrial,
computing, and data-communications applications.
Configurations may be stored in on-chip One-Time
Programmable (OTP) memory or changed using I2C
interface. This is IDT’s fifth generation of programmable clock
technology (VersaClock® 5).
The frequencies are generated from a single reference clock.
The reference clock can come from one of the two redundant
clock inputs. A glitchless manual switchover function allows
one of the redundant clocks to be selected during normal
operation.
Two select pins allow up to 4 different configurations to be
programmed and accessible using processor GPIOs or
bootstrapping. The different selections may be used for
different operating modes (full function, partial function, partial
power-down), regional standards (US, Japan, Europe) or
system production margin testing.
The device may be configured to use one of two I2C
addresses to allow multiple devices to be used in a system.

Differential clock input. Weak 100kohms internal pull-down.
Complementary differential clock input. Weak 100kohms internal pull-down.
Crystal Oscillator interface output.
Crystal Oscillator interface input, or single-ended LVCMOS clock input. Ensure that
the input voltage is 1.2V max.Refer to the section “Overdriving the XIN/REF
Interface”.
Analog functions power supply pin.Connect to 1.8V to 3.3V. VDDA and VDDD should
have the same voltage applied.
Input clock select. Selects the active input reference source in manual switchover
mode.
0 = XIN/REF, XOUT (default)
1 = CLKIN, CLKINB
CLKSEL Polarity can be changed by I2C programming as shown in Table 4.
Enables/disables the outputs (OE) or powers down the chip (SD). The SH bit
controls the configuration of the SD/OE pin. The SH bit needs to be high for SD/OE
pin to be configured as SD. The SP bit (0x02) controls the polarity of the signal to be
either active HIGH or LOW only when pin is configured as OE (Default is active
LOW.) Weak internal pull down resistor. When configured as SD, device is shut
down and the single-ended LVCMOS outputs are driven low. When configured as
OE, and outputs are disabled, the outputs can be selected to be tri-stated or driven
high/low, depending on the programming bits as shown in the SD/OE Pin Function
Truth table.
Configuration select pin, or I2C SDA input as selected by OUT0_SEL_I2CB. Weak
internal pull down resistor.
Configuration select pin, or I2C SCL input as selected by OUT0_SEL_I2CB. Weak
